What species has the greatest number of electrons I- or Cu2 plus or Fe3 plus or Au or Hg?
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
What is the difference between Fe2 plus and Fe3 plus?
Fe3+ is smaller. Its ionic radius is 63 pm, while Fe2+ has an ionic radius of 77 pm. (For comparison, the Fe atom has a radius of 140 pm.) This is because the outermost electron in the 2+ ion is pulled off to form the 3+ ion. This outermost electron was the most weakly held. The remaining electrons are closer to the nucleus.
Is an oxidation half-reaction A. Fe2 plus Fe3 plus plus e- B. Fe3 plus plus e- Fe2 plus C. Fe(s) Fe(l) D. Fe plus 2e- Fe2 plus?
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
Which is the least likely to be reduced zn2 fe3 fe2 cu2?
Fe3 is the least likely to be reduced because it has the highest oxidation state among the listed elements, making it less prone to gaining electrons and being reduced.
Which is most likely to be reduced Fe2 Cu2 Fe3 or Zn2?
Answer this question… Fe3+
How many unpaired electrons in (d) subshell in ferric Fe3?
5 unpaired electrons There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.
How many unpaired electrons are in Iron-III?
There are 5 unpaired electrons in Fe^3+ in its ground state.
What.........Fe2O3 is named iron (III) oxide because it contains . a. three unpaired electrons c. three iron atoms b. Fe3 plus ions d. O3 plus ions?
b. Fe3 plus ions
How many electrons has an atom of iron lost to become an Fe3 plus ion?
it should lose 3 electrons
How many 3d electrons does an Fe3 plus ion have?
The answer is 3. Fe -> Fe3+ + 3e
How many electrons does iron III have?
Iron III, or Fe3+, has lost three electrons to become positively charged. Therefore, it has 23 electrons in its neutral state but only 20 electrons in the Fe3+ state.
What species has the greatest number of electrons I- or Cu2 plus or Fe3 plus or Au or Hg?
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
What is fe3 plus plus cl?
FeCl3
How many protons neutrons and electrons in Fe3?
The Fe(3+) cation has 26 protons, 30 neutrons (for the isotope Fe-56) and 23 electrons.
What is the difference between Fe2 plus and Fe3 plus?
Fe3+ is smaller. Its ionic radius is 63 pm, while Fe2+ has an ionic radius of 77 pm. (For comparison, the Fe atom has a radius of 140 pm.) This is because the outermost electron in the 2+ ion is pulled off to form the 3+ ion. This outermost electron was the most weakly held. The remaining electrons are closer to the nucleus.
What transition metal has 30 electrons?
Iron (Fe), 26 electrons in neutral atom, 23 in Fe3+. Rust, Fe203 has Fe3+ ions.
What is the electronic configuration for Fe3?
The electronic configuration of Fe3+ is [Ar] 3d3 4s2 or 2, 8, 11, 2
